UPHOLSTERING DEVICE- Application led May 7,

rIhis invention relates to upholster-ingdevices and proposes the construction of a Lachine for making that type of cushions characterized by having a square or lrectangular eifect, and in which metallic springs are or may be embedded in an even layer of fibrous or other appropriate form of" stuliing.

One of' the objects of the invention 1s the construction of a conformer or pan capable of' a range of lateral extensions so that it may be made wideror narrower than the lateral dimension of' the fini-shed cushion. In operation, the stuffing, including` the springs, if such are to be used, is placed within4 the. pan when it is in expanded position. The pan is then contracted laterally compressing the stuiiing to a size a little narrower than the finished cushion. The casing or cushion cover is then slipped over the pan and the stuthng forced out into the casing either manually or by other suitable means, pushingV the cushion cover off of the pan, said stuffing expanding to tightly lill the cushion cover, the shape given to. the stuiiing by thepan being preserved in the finished cushion.

Another object of the invention is 'to simplify the construction of cushion making machines, while at the same time increasing their practial eiiciency.

Other objects will appear as the description develops.

In the drawings Figure 1 is a perspective view of a device constructed according to the principles of my invention.

Figure 2 is an end elevation of the same showing the stuffing receiving pan in eX- panded position.

Figure 3 is a view similar to that of Figure 2 showing the parts in contracted position.

Figure 4 is a plan view.

Figure 5 is a plan view of the frame and compressing mechanism.

Referring now in detail to the several figures, the numeral l represents in general a rigid frame comprising top and bottom members 2 and 3 respectively, connected by an end member t. Said frame members function as a support for fiXedly carrying one part of the cushion receiving pan, presently to be described, the other part being slidable laterally upon said frame. An intermediate frame member 5 is spaced in 1924. Serial No. 711,740.

parallel relation Yto the bottom member 3, said frame members forming a guideway for a screw block 6. The screw block .is formed with a threaded bore into which extends the threaded screw stem 7 which screw 'stem is rotatably but non-reciprocably sup-ported upon the end frame member 4 by means of a collar 8 with which said screw stem i's swivelly connected. An operating handle 9 is carried by sai-d screw stem at a convenient point external to the frame. By rotating the screw stem the screw block 6 advances in either direction with-in the guideway formed by the frame members 3 and 5, its movement in any ontward direction being limited by any suitable means such as the stop 10.

The stufling receiving' pan comprises two parts, each consisting of flat plates 11 and 12, bent up to form sides 13 and 111. Cover plates 15 and 16` are hingedly connected to the free edges of said sides. The. bottom plates 11 and 12 and the cover plates 15 andV 16 are arranged in overlapping relation as shown at 17 (Figure The pan is preferably open at both ends. One iart'of the stuffing receiving pan, thaty is to say in thisl instance, that part including the bottom and cover plates 11 and 16 is attached to the screw block 6t by sui-table means such as: the screws 18, but free with respect tot the frame so that when the screw block is reciprocated in its guideway this part ofthe stuliing receiving pan will perform a telescopic movement with respect to that part of the stuffing receiving pan constituted by the bottom and cover plates 12 and 15 and the side 13, which latter part is fixed to the frame. Ry this means the stuffing receiving pan is laterally eXtensible through a range of movement which includes a minimum size slightly smaller than the width of the finished Vcushn ion and a maximum width somewhat, and preferably considerably, greater than the width of the finished cushion.

One end of each of the pans projects beyond one side of the frame, thus facilitating the application of the open end of a cushion cover thereto.

In the operation of my improved upholstering device, the handle 9 of the screw stem 7 is turned in such a direction as to ad- Vance the screw block 6 toward the outer end of its guideway, extending the parts of the stuffing receiving pan to a width greater than that of the linished cushion, as shown in Figure 2. The cover plates 15 and 16 are then raised and a layer of stutiing arranged in place in the form of a nest for receiving the springs. In some instances where springs are not to be used the pan is simply filled with stuffing. After the springs are set upon the initial layer of stuffing, another layer of stuffing is placed upon them, said layer cooperating with the underneath layer il in forming a resilient fibrous padding covering the sides, ends, top and bottom of the springs. 'Ihe cover plates 15 and 16 are next closed, being locked by any suitable means, not shown, it desired, and the screw stem 7 is turned to draw the screw block 6 inwardly contracting the width of the stuH- ing receiving pan. This has the effect of compressing the stuiiing, making it fill all the corners and edges of the pan squarely and in a uniform manner. Contrac-tion of the pan is continued to the point at which it is slightly smaller in Width than the finished cushion. Thereupon the casing or cushion cover 19 is slipped over the lower end of the stuffing receiving pan and the stuiiing then pushed out of the pan either manually or by suitable mechanical means. As said stuffing contacts with the bottom ot the cushion cover it pushes the same oli from the cushion receiving pan, this action progressing until the entire body of stuiiing including the enclosed springs is within the cushion cover and the latter has been pushed completely away Vfrom said pan. The stuffing, being freed from the compression of the walls of the pan, expands uniformly into resilient Contact with all parts of the cushion cover, the shape given to the stuffing by said pan being preserved in the finished cushion.

The fixed relation of one of the parts of the stumng receiving pan to the frame not only permits said part to act as a support for the slidably mounted part, thereby adding considerable rigidity to the device, but the side of the fixed part constitutes a fixed datum or base against which to build up the fibrous layers of stufng by compressing said stuiiing by hand from time to time against said fixed side in determining how much stufiing should go into the cushion.

It will be understood that various changes may be made in the form and relation of parts to suit different requirements of use, and that the invention, therefore, is not limited to the precise details of constru't-ion and arrangement shown.

Having described my invention What I claim as new and desire to secure by Letters Patent, is

A portable upholstering device including a frame comprising fixed side and end members, a slide in said frame and movable from end to end thereof, said slide having a screw-threaded bore, a screw swivell-ed in one of the end members of said frame and engaging the bore of said slide, and a pair of pans each comprising a side, a bottom integral with said side and a top hinged to said side, one of said pans having its bottom secured to the upper part of said frame and the other of said pans having its bottom secured to said slide with its open side in telescopic relation to the open side of said firstenamed pan, said pans each having one end projecting beyond one side of said frame.

In testimony whereof I have hereunto set my hand. Y
